Sheet 2. Name Gouldbusk is here applied to limestone beds and included thin shale that were called Horse Creek limestone by Drake. Sellards (Univ. Texas Bull., no. 3232, 1933) pointed out duplication by Drake in use of this name, as applied to beds in his Strawn division farther east in Colorado River Valley and to limestone, now considered Permian(?) in age, exposed in Coleman County. Sellards restricted application of Horse Creek to beds in Strawn sequence but did not rename the upper beds, which confusingly have continued to be called Horse Creek (Cheney, 1940; King, 1942, AAPG Bull., v. 26, no. 4).
